Medieval tower partially collapses in Rome critically injuring worker and trapping another

A medieval tower in the heart of Rome partially collapsed during renovations of the structure, critically injuring one worker and trapping another.

A medieval tower in the heart of Italy's capital, near the Roman Forum ruins, partially collapsed on Monday during renovations of the structure, critically injuring one worker and trapping another, authorities said.

Hundreds of tourists watched as firefighters used a mobile ladder to bring a stretcher to the upper level of the Torre dei Conti to rescue the worker who remained trapped.

During the rescue attempt, another part of the structure partially collapsed, sending up a cloud of debris and forcing firefighters to quickly retreat.

Firefighter spokesman Luca Cari confirmed that the one remaining worker remained trapped hours after the initial collapse. He added that a rescued worker was being treated in critical condition and that another three workers were rescued unharmed.

The initial collapse happened some time before noon, and did not appear to have involved any bystanders.
